SPECIFICATION forming part of Letters Patent No. 379,188, dated March 6,1888.

Application filed Juy 2,1887. saranno. 243,239. (No modem To aZZ whom itmay concern'.

Be it known that I, MATTHEW VIERENGEL, a subject of the Emperor ofGermany, residing at Brooklyn, in the county of Kings and State of NewYork, have invented new and useful Improvements in Cylinder Printing-Machines, of which the following is a specilication.

This invention relates to improvements in printing-presses, as set forthin the following specication and claims, and illustrated in theaccompanying drawings, in which- Figure l is a side elevation of aprintingpress. Fig. 2 is aside elevation seen from the opposite sidefrom that shown in Fig. l, and the sheet-delivery apparatus beingremoved. Fig. 3 is a detail view of an impression-cylinder and adjacentparts, partly in section and parts being broken away. Fig. 3 is a detailview of the parts shown in Fig. 8 with the detent withdrawn from theimpression-cylinder. Fig. 4 is a rear elevation of a printing-press.Fig. 5 is a front elevation thereof. Fig. 6 is a detail side elevationof mechanism for vraising the cylinder. Fig. 7 is a section in the plane.t x, Fig. 6. Fig. 8 is a view similar to Fig. 6, showing the parts insomewhat different relative position. Figs. 9 and l() are views similarto Fig. 6, showing the parts in different relative position.

Similar letters indicate corresponding parts.

In the drawings, the letter A indicates a frame.

B is an impression-cylinder, the teeth C of which are adapted to gearinto the rack D of the type-bed E. The type-bed E is adapted to travelback and forth, being supported on rollers F, suitably applied for thatpurpose.

The rack G of the type-bed is engaged by the teeth of the wheel H. Theteeth of the wheel H engage a fixed rack, I. A connecting-rod, J,extends from the wheel H to the crank K on the shaft L. To the shaft Lis secureda toothed wheel, M, which gears into a toothed wheel, N, onthe shaft O. Said shaft O is provided with a fly-wheel, P, and withpulleys Q, one of which is fast on the shaft O and the other of which isloose thereon. By

applying a belt or other suitable means to the fast pulley Q the shaft Ocan be rotated.

On the shaft L are cams R, having camgrooves S extending across them,Fig. 2. The

restin holes or recesses in the supportingarms X. Said arms X areadapted to move back and forth vertically, and said arms have seats Y,Fig. 3, adapted to engage supporting rims or wheels' Z, Figs. 3 and 4,on the shaft h of the impression-cylinder B. One or more spring-actuateddetents, ci, Fig. 3, are secured to the supporting-arms X, and saiddetents are adapted to engage recesses in the supporting-rims Z, andthereby prevent the cylinder B from turning.

The/boxes g of the cylinder -shaft h are adapted to slide in ways formedin standards Z rising from the fra-me A. Capsf are bolted or otherwisesecured to the standards Z, and a toggle-joint, ij, isjointed to thecapsfand to the boxes g. Levers or arms 7c are applied to operate thetoggle-arms ij.

To the supporting-arms X or to the seats Y are secured pivots b,supporting hooks e. Pins e, projecting from the standards Z, enterguide-slots d in the hooks c. On the shaft L is a cam, m, Fig. 6, whichengages a roller, n, on the arm o. The free portion of the arm o can becaused to rest on the pin or rest p, fixed to the frame A, or on the pinor rest g, projecting from the arm s ofthe lever Z s. Said lever Z s isadapted to swing about the fulcrum 1' on the frame A, and the arm Z issecured to the lever Z s by a joint, m. A spring, a', holds the arms Z sin the position shown in Figs. 6 and 8.

To the arm o is secured a link, t, by means of a pivot, u. The pivot oconnects the link t to the arm w'. A pivot, a', connects the arm w tothe weight b or to a crank-arm connected to said weight b. The weight bis adapted to swing about the shaft i', so as to rest either in theposition shown in Fig. 6 or in the position shown in Fig. 8 in dottedlines. The shifting of the weight is accomplished b means of thetreadle-arm f', pivoted at g to the frame of the machine. A link, d', ispivoted at e to the treadle-arm f', and at c to a crankarm of the weightb. By properly actuating the treadle f the weight b' can be swung so asto rest either in the position shown in Fig. 6 or in the position shownin Fig. 8. Said arms w o are intended to bring the detents 0', Figs. 6and 8, into or out of engagement with the lever UW, as will behereinafter set forth. Said detents o swing on pivots p', suitablysecured to a fixed part of the press. Pivots or pins g connect thedetects 0' to connectingarms 1". Pins or pivots s connect the arms r tocranks t', keyed to a shaft, a', which receives motion from a lever ordetent actuator t', keyed to said shaft u'. To'the lever n is fixed abracket, b2, having stops c2. A shaft, lw, Fig. 7, is adapted tooscillate in an eye or seat in the lever 'o'. A uger, a2, is fixed tothe shaft w', and a lug, d2, projecting from said ringer a2, is adaptedto engage the stops o2, thus limiting the motionA of the finger a2in onedirection or another, as seen in Figs. 6 and 8.

A collar, f 2, Fig. 7, sits loosely about the shaft w', and to saidcollar is fixed a weight, j2. As the collar is turned .on the shaft w',the weight j2 is swung to one side or the other, as seen in Figs. 6 and8. In swinging to one side or the other, the weight j2strikes one oranother of the fingers e2, which are fixed to the shaft w', thus turningsaid shaft and causing the finger a2 to rest against one or the other ofthe stops c2. To the collar f2 are fixed four hooks or hooked plates,g2. Two of said hooks are adapted to be engaged by lugs h2 on the arm orrod rw, and two of said hooks are adapted to be engaged by lugs i2 onthe arm or rod o. To the crank K is secured a lug, 7a2, and the relativepositions of the lingers a2 and lug k2 are such that at certain timesthe 1ug7t2 can be brought against the tinger`a2 by the revolution of thecrank, such contact of the lug k2 and linger a2 being made to operatethe lever fv, as will be hereinafter set forth.

On the frame of the press are secured ways Z2, Figs. l and 5, on whichthe rollers m2 of the sheet'- delivery mechanism travel back and forth,so as to carry the sheets from the impression-cylinder B to thereceiving board or table p2. The rollers or sheet-delivering carriage m2are actuated bythe links or arms r2 s2. The arms r2 are keyed to theshaft t2, which is adapted to turn in bearings in thearms s2. A spring,a2, Fig. 5, is coiled about the shaft t2, and said spring is tirmlysecured to one of the arms s2 and also to the shaft t2. The arms s2 arekeyed to the shaft c2 of the bevel gearwheel 102. A shaft, B', has abevel-gear, A', engaging the bevelgear 102, and another hevel gear, C',engaging the bevel-gear D of the shaft E.

The bevelgear F of the shaft E gears into the bevel-gear G of the shaftI', which is keyed to the toothed wheel H', to which an oscillatingmotion is imparted by the rack-bar J. Said rack-bar J is oscillated bythe crank-pin L on the cam B.

The free end of the rack-bar J is adapted to move upon and to besupported by a roller, K', on an arm, M', Fig. l. Said arm M- is fixedto a shaft stud or pivot, N, adapted to turn in afixed part of themachine. From said shaft vN extend two arms, O' P. The roller Q of thearm P rests on the edge of a disk or wheel, R', keyed to the shaft l.Said wheel R'keeps the armsP M in such position that the rack-bar J isheld in gear with the toothed wheel H. In the wheel Ris a notch, S, andwhen the roller Q' falls into said notch S the rack-har J and thegear-wheel H are out of gear and the motion of the wheel H and of thesheet-delivery mechanism stops. To one of the lifting-arms X is secureda lug, T',

Fig. l, which, when the arm X descends, will ceive a sheet,th uslessening the distance which the sheet-delivery mechanism has to travelin carrying a sheet from the cylinder B to the boardp2.

The pivot V', to which the arms Uare fixed or keyed, is made in form ofa shaft, as seen in Fig. 5, to which shaft is keyed or fixed an arm, A2,Figs. l and 5, connected by a pivot, B2, to a pitman, C2. Apivot, D2,connects the pitman U2 to a bell-crank lever, E2 F2, swinging about apivot, G2, and having its arm F2 provided with a weight, H2, and with aroller, I2. The roller l2 rides on a cam, J2, on the shaft L, and as thelow part of the cam comes into proximity with the roller l2 the weightH2 causes the arm F2 to descend, after which the high part of the cam J2raises the arm F2 again. This rising and falling of the arm F2 causesoscillation of the pitman C2 and of the table p2. The motion of thetable'p2 can be arrested by a detent, K2, Fig. 1, swinging about apivot, L2, which detent has a notch, N2, that may be caused to engagethe pivot D2, and thus arrest the motion ofthe bell-crank lever E2 F2.The detent IOO IIO

K2 is actuated by an arm, M2, secured to one ofthe levers or arms t orto their shaft u', and when said arms tand shaft u are swung to theposition shown in Fig. 8 the arm M2 is actuated so as to cause thedetent K2 to assume such position that it can engage the pivot D2. Thearm M2 is made in form of a springarm, so that if necessary t-he det-entK2, when supported bythe arm M2, can yield sufficiently to allow thepivot D2 to glide into engagement with the detentnotch N2, after whichthe spring'arm M2 will press the notch N2 into engagement with the pivotD2, and will keep said parts in such engagement.

The receiving-table p2 is provided with a ledge, O2, at its inner edgeto prevent the sheets from gliding off said table. The outer or freeedge of the table p2 is open, so as to enable the sheets to be easilyremoved therefrom, when desired. l To prevent sheets coming from thedelivery mechanism onto the board or table p2 from gliding off the frontedge of the table p2 at improper times, I provide stop-fingers P2,swinging about a shaft or pivot, Q2. Aweight, R2, tends to keep saidfingers in an upright position. The pressure of the table p? upon thefingers P2 will hold said fingers in the position shown in Fig. l; butwhen the free edge of the table p2 has swung past said lingers l?2 inits motion toward the cylinder B, then the weight B2 causes the iingers'P to stand up, so

as to stop sheets from gliding 0H the free edge of the table p2. Thereturn of the table p2 to the position shown in Fig. l will press thetingers l?2 back to the position shown in said-Fig. l. When not in use,the table p2 can be swung about the pivot Y until a pin or projection,Si, upon said table is caught and held by the hook S2, swinging aboutpivot X.

By connecting a pin or projection, S3, Figs. 1 and 5, to the tablepi, insuch a position that when the table p2 is swung so as to carry said pinS3 toward the hook Sisaid hook will engage and hold said pin, said hookcan be made to hold the table up or in a raised position.

In Fig. 5 the hook S'l is shown as partly broken away, so as to exposeto view partslying behind said hook.

On the impressionvcylinder B is a gear-segment, Zi, Fig. 4. A rack-bar,T2, Figs 2 and 4, is adapted to engage said segment at certain timeswhen the rack or racks D of the typebed E are out of gear with the gearwheel or wheels C of the cylinder B, as seen in Fig. 2. The rack-bar T2is pivoted at U2 to the lever V2, fulcru med at W2, and the roller X2 ofwhich lever is actuated by a camvgroove, Y2, on the shaft L.

The operation of the machine is as follows: Suppose the parts to be inthe position shown in Fig. 2, and the shaft L with the crank K revolvingin the direction of arrow 1, Figs. l and 2. The action of the crank Kwill actuate the wheel H, so as to cause the type-bed E to travel fromits position shown in Fig. 2at the front of the press toward the rear ofthe press and back again to its starting-point. At the moment thetype-bed moves forward the roller T enters the cam-groove S, thusallowing the cylinder B to descend, sov as to bring its gears C Z2 intoposition to engage the racks D T2. The hook c, acting on the arm k,locks the toggle-joint ij, as seen in Fig. Si, and the descent ofthe armX and seat Y draws the detent a out of engagement with the cylinder B.The cylinder B is then revolved in the direction of arrow 2, Figs. l and2, rst by the rack-bar T2, which is moved by the cam Y2, and whichrackbar acts on the segment Z2, and afterward by the racks D, acting onthe gears C. The grippers on the cylinder B seize a sheet from thefeed-board q? and carry it in the direction of arrow 2, so that saidsheet is brought into contact with the type, stone, or plates on thetype-bed and receives an impression. As the cylinder B continues itsrevolution, the cylinder-grippers release the edge of the sheet in timefor said edge to be seized by the grippers n ofthe delivery mechanism,the operation of type-bed starts on its return motion to resume theposition shown in Fig. 2, the rollers or vrollerT passes out of thecam-groove S and comes to rest upon the outer edge of the cam R, therebylifting the cylinder B and causing it to rest on the seats Y, while thedetent a prevents turning of the cylinder. The typebed E and therack-bar T2 now return to their respective starting-points withoutactuating the cylinder B, which has been raised out of gear with theracks D T2. W'hen the type-bed and rack T2 have reached theirstarting-point, the cylinder B descends, and the operation of printinganother sheet is commenced.

The sheet-d elivery is operated as follows: The cam R with the crank-pinL revolve in the direction of saidarrow l and at first actuate therack-bar J', so as to cause the gearwheel w2 to turn in the direction ofarrow 3, Fig. 1, until the arms s2 r2 have respectively assumed theposition shown by the dotted lines 4t and 5. This motion of the arms s2r2 causes the spring u on the shaft t2 to be twisted. This torsion ofthe spring u2, togetherwith the momentum of the rollers mi, causes thefree end of the arm ri to swing forward from the position shown by thedotted line 5, and a sufficient distance toward the table p to get pastthe dead-center. The rack-bar J now moves in the opposite direction,causing the wheel 102 to revolve in the direction opposite to that ofarrow 3, thus carrying the arms 32.13 to the position shown by thedottedlines 6 and 7, Fig. l. The grippersu2 ofthe deliverymechanism,which have seized the printed sheet and taken it off thecylinder B, now rest above the table p2, and said grippers are opened bythe nger o2 and release the printed sheet, which falls onto the tablepg.Said table p2 has mean while been swung toward the cylinder B for acertain distance, so as to be in position to squarely receive the sheetwhen it is released by the delivery mechanism, thereby also lesseningthe distance the delivery mechanism has to travel to deliver a sheet tothe table p2. After receiving a sheet from the delivery mechanism thetablep2 moves forward or away from the cylinder Bto itsstartingpoint.The wheel w2 continues to revolve in the direction opposite to that ofarrowS until the arms s2 ri have reached the position shown by thedotted lines 8 and 9, whereby the deliveryrollers m2 are caused to movea certain distance toward the cylinder B. The momentum of the rollers m2and the torsion of the spring u2 carry the arm r2 sufficiently far fromthe position shown by dotted line 9 and toward the cylinder B to causesaid arm 1 to pass the dead-center. The rack-bar J now reverses itsmotion and resumes its original` motion, thereby vcausing the wheel 102to turn in the direction of arrow 3, and bringing the arms s2 r2 back tothe position shown by full lines in Fig. 1. The rack-bar J is duringthese motions kept in gear with the wheel H by the edge of the disk orwheel R and by the lug T on one of the arms X, which lug presses uponthe arm O at the proper times to prevent the roller Q' entering thenotch S, whereby the rack J would-be thrown ont of gear with the wheelH.

Sometimes it may be desired to keep the cylinder B out of gear with thetype-bed rack D while the type-bed passes several times back andforth-as, for example, when it is desired to thoroughly distribute inkover the type. For this purpose the treadle f Fig. 6, is actuated, so asto throw the weight b from the position occupied by it in Fig. 6 to theposition occupied by said weight in Fig. 8, thereby causing the arm w todraw the nger ft2 away from the stop c2, supporting said tinger in Fig.6 and bringing said finger to rest against the other stop cIl on thebracket b2. This motion of the finger a2, it should be noticed, does notimpart motion to the lever n', but said lever c remains in the positionit occupies in Fig. 6 until the pin or lug k2 on the crank K strikesagainst the finger ft2, which, by reason of its changed position, nowrests in the path of said lng k2. The pressure of the lug k2 on thefinger a2 will swing the lever fv away from the crank-shaft L, therebymoving the arms t r so as to move the detent o into engagement with thearm U, as seenin Fig. 8. Vhcn the lever o has been moved to the positionshown in Fig. S, the center of gravity of the lever o has been carriedso far in the direction away from the shaft L that the weight of thelever o', with the weight of the parts connected to said lever, willhold the lever in the position shown in Fig. 8,when the projection h'zhaspassed the fingerctz. Said detent 0 now prevents the cylinder B fromdescending upon the type-bed, as said detent o holds the levers UWV andthe lifting-arms X in their raised position to hold the cylinder B awayfrom the type-bed. As said detent o' prevents the armsX from descending,the lug T' on one of t-he arms X is prevented from pressing onto the armO', and as soon as the roller Q', now comes opposite the recess S in thedisk R. the rack-bar J drops ont of gear with the wheel H' and themotion of the delivery mechanism is stopped. Also, when the arms t arein the position shown in Fig. Sthe arm M2, Fig. 1, presses the detent K2into engagement with the pivot D2, so as to stop the motion of thepitman CAZ and of the receivingtable p2. The type-bed will now continueto pass back and forth, but without any movement taking place ofthecylinder B, thesheetdelivery mechanism, and the receiving-table p2. Toreturn the parts to the position shown in Fig. 6, the treadle f' isactuated, so that the weight b is swung` back to the position shown insaid Fig. 6, whereby the finger ai is swung from the stop c2, againstwhich it rests in Fig. 8, so as to rest against the opposite stop, c2,whereupon the lug k2, upon the revolution of the crank K, presses uponthe finger a2, so as to press the lever c from the position it occupiesin Fig. 8 toward the crank-shaft L, thus bringing said lever v' to theposition shown in Fig. 6, when the detent o releases the arm U andallows the roller T to enter the cam-groove S at certain times when thecam R revolves, thus allowing the cylinder B to descend upon thetype-bed E.

It should be noticed that the movements of the weight b', actuating thearm w, do not directly actuate the finger a2,but said arm w actuates theweight j2 on the lever c', and as said weight j2 is swung to theposition shown in Fig. 6 vor Fig. 8, said weightj2 strikes against oneor the other of the fingers e2, and thereby presses the finger a'l toone side or the other.

At times it may be desired to have the cylinder B remain out of gearwith the type-bed during each alternate reciprocation back and forth ofthe type-bed. To accomplish this object the pin k', Figs. 6 and 7, isslid into the arm jnntil said pin occupies such position that when theweight b' is swung to the position shown in Fig. 8 the pin It willdepress the arm Z and raise the arm s, so as to bring the pins t2 of thearm o into position to engage the hooks g2, while at the same time thelink t raises the arm w, so as to take the pins hZ out of engagementwith the hooks g2. \Vhen the weight b is now thrown over from theposition shown in Fig. 6 to the position shown in Fig. 9, the linger c62is moved to the position shown in Fig. 9 by the arm w before the pin 7creaches the lever l s. The parts will then be in position shown in Fig.9. If thereafter the finger a? is to be oseillatcd, then the arm o,being oscillated by the cam m, will throw the finger ai to the positionshown in Fig. 9in dotted lines, or to the position shown in said Fig. 9in full lines, as may be required. Vhen the parts are in the positionshown in Fig. 9, and the crank K revolves, then the lug L2 on said crankwill strike against the finger ai and will swing the lever t to theposition shown in Fig. l0, so that the detent o will hold the lever U Wand will keep the cylinder B raised from the type-bed. The lever o' anddetent o will remain in this position during one entire revolution ofthe crank K, during which revolntion the type-bed moves once back andforth. When the crank K begins its second revolution, the arm 0 willhave moved the iinger a.2 back to the position on the lever o',indicated in dotted lines in Fig. 10, and upon the lug k2 striking saidfinger a the lever t' will be moved back to the position shown in Fig.9, thereby causing the detents o to release the levers U W', whereuponthe cylinder B can descend upon the type-bed and the operation ofprinting can be proceeded with. An advantage of having the cylinderB ingear with the type-bed only during each alternate oscillation of thetype-bed is, that the ink can be thoroughly distributed over the type orplates on the type bed before any printing is done. The spring-actuatedarm l of the lever Zs will allow sutcient yielding of the parts toprevent breakage in case the parts should at timesnot be in suchvposition that the lever Z ls can cause the pins or lugs i2 to engage thehooks g2.

The descent of the arms X, it will be noticed, will cause the hook c,Fig. 3, to engage the lever k and actuate the toggle-joint i j, so as topress the cylinder B rmly against the type bed in the operation ot'printing.

In place of only one spring, ui, applied to the arms s2 ri, as seen inFig. 5, two springsone being near each extremity of the shaft 15- maybeapplied.

By having the sheet-delivery carriage, with its ways and its actuatorw?, located above the body of the press the motions of said' parts willnot prevent or interfere with access t0 the body of the press.
